Abstract

PROBLEM TO BE SOLVED: To repeat a connection with a private terminal based upon a characteristic private terminal call number by allowing a voice constituting element to request a caller to input a postselection instruction when a connection with the caller is established and converting the postselection instruction inputted by the caller to a repeating signal to the private terminal to be selected. SOLUTION: When a repeating matrix 2 accepts an incoming call, a sequence control system 3 outputs a notice message from a voice constituting element 5 to transmit voice information to the caller. The caller is requested to input the postselection instruction including the discrimination code of a private terminal to be selected. A discrimination unit 4 receives and identifies the postselection instruction inputted by the caller, converts it into an electron control signal, and sends it to the sequence control system 3. The sequence control system 3 takes in the number of the private terminal to be selected to generate a repeating signal and sends it to the repeating matrix 2. The repeating matrix 2 makes a connection with the object private terminal with the repeating signal.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preparing a direct communication selection function for a communication device which cannot directly select a direct communication to a local terminal using a unique local terminal call number.

[0002]

BACKGROUND OF THE INVENTION Home telecommunications devices are usually only connected to a central office connection and make incoming calls in a fixedly programmed scheme. It is distributed to the local terminal connection unit. In this way, incoming calls are sent, for example, to all local terminals or only to selected local terminals. Various transmissions in the sense of post-selection with an extended calling number have not been possible before. An auxiliary device that covers a certain range is I
Created by the introduction of MSN (Multiple Subscriber Number) for SDN. Here, at least 3 and at most 12 call numbers are I
Assigned to SDN central office connection. However, such a method presupposes the existence of an ISDN telephone line, and there is a problem of cost in the case of three or more calling numbers.

[0003] Another disadvantage of this technique is that all the local terminals are away and no connection is made, and the information is left as it is unless the call responder is connected to the communication device. It is therefore an issue to prepare for the possibility of realizing a direct selection function for such a communication device and to present a method and a device therefor. The problem is solved by a method for preparing a direct selection function having the following features in a communication device in which direct selection to a local terminal cannot be directly performed by a unique local terminal call number. 1.1 The incoming communication connection is automatically accepted by the communication device. 1.2 The audible user guide instructs the caller on the direct or post-selection function and requests the caller to enter a post-selection command. 1.3 The post-selection command is a multi-frequency code signal or a signal input as a voice command, which includes the name of the user of the corresponding terminal or the local terminal to be selected, such as the local terminal number, respectively. Contains the assigned characteristics. 1.4 After being input, the selection command is transmitted to the communication device as an audio signal. 1.5.1 The selection command after being input as a multi-frequency code signal is converted into an electronic relay signal containing the electronic characteristics of the local terminal to be selected, or 1.5.2 input as a voice The post-selection command is converted to an electronic relay signal, where the audio signal is assigned to a predetermined audio pattern associated with the local terminal, an electronic relay signal is created, and its identification is made. Electronic terminal characteristics. 1.6 The relay signal electronically simulates manual relaying by input of a key command of the communication device terminal, whereby the communication device relays the connection to the local terminal corresponding to the post-selection command.

[0004]

[Means for solving the problem] In order to solve the problem,
An apparatus for performing the method is essential, which has a sequence control system and an identification unit. The sequence control system issues a control signal when a call comes in, whereby the communication device establishes a connection with the caller. When a connection is made, the sequence control system directs the output of a notice stored in memory for the audio component. This voice component informs the caller of the post-selection function and requests the caller to enter a corresponding post-selection command. The notice is mainly determined by the user,
It informs the caller which subscriber is to be connected to which local terminal and which post-selection command is to be entered. The post-selection command can be input as a multi-frequency code signal, which is generated by keying in at the caller's terminal and transmitted as a voice signal to the called communication device. The post-selection command can also be an audio signal, a spoken word, which is transmitted to the communication device in a known manner. In order to receive and convert such a multi-frequency code signal or audio signal, the identification unit comprises a multi-frequency receiver or an audio identifier, possibly both.

[0005] The multi-frequency receiver converts the selection command, which has been input as a multi-frequency code signal, into an electronic control signal, which is basically a digital signal, in a known manner and transmits it to the sequence control system. . Since the post-selection command includes the characteristic clearly assigned to the local terminal to be selected, the converted control signal also includes the electronic characteristic of the selected local terminal.

In the case of a post-selection command input as a voice signal, the post-selection command is sent to the voice identifier as a voice signal,
When mainly digitized, the audio signal is compared with a predetermined audio pattern stored in digital form in a memory and associated with the local terminal. The post-selection command is assigned to a private terminal whose associated voice pattern indicates the maximum match with the post-selection command. The voice identifier guides the identification result in electronic form to the sequence control system as a basically digital control signal. The sequence control system converts the signal conveyed by the identifier unit and containing the electronic characteristics of the local terminal to be selected into a relay signal. This relay signal
The selection is made so as to correspond to a control signal generated when manual relay is performed by the communication device. Such a relay signal is composed of the control signal “switching bridge” and the identified local terminal number. In such a device, a post-selection function according to the invention is provided, whereby the direct selection function is simulated, and after the communication device receives the relay signal, the relaying or switching of the connection is performed by the communication device in a known manner. Done. The relay matrix of the communication device, for example, places the incoming connection from the outside on the ground side, attempts to connect to the desired local terminal, and, when the receiver is picked up at the local terminal, combines the connection to the local terminal with the external connection.

In a further development of the method, if the relayed connection is not accepted within a predetermined time or after a predetermined number of bell codes, an initial state before the relay is automatically created. That is, the local terminal does not respond. Then, a notification and request for inputting the post-selection by inputting the subscriber terminal characteristics or the name of the subscriber assigned to the predetermined premise terminal, post-selection instruction, conversion to an electronic relay signal, and post-selection instruction Is switched again to the local terminal corresponding to the connection. The local terminal to be selected may then be a call responder.

In another design of the method, if the relayed connection is not accepted, the initial state is automatically re-established and the connection is automatically relayed to the call answering machine or the call answering The function is activated. An advantage of the device according to the invention is that the call answering memory is partitioned into storage areas which are allocated to the individual local terminals. The local terminal, which retains the information, is converted into an electronic control signal in the manner described above by the identifier unit and is selectable by a caller input of a multi-frequency code signal or a voice signal evaluated by the sequence control system. . When the information activates the call answering component,
It may be automatically assigned to a local terminal where the connection was not successfully relayed before.

In order to secure access, the storage area of the call answering machine memory is designed to be accessed directly from the associated local terminal and from other local terminals after inputting the access code (PIN). The device of the present invention can be an integral component of a communication device. That is, it can be used as the order of direct switching to the communication device.

If the device is designed as a component independent of the communication device in order to enable a direct selection or post-selection function in a communication device already in operation, and if it includes the switching sequence described above, This is advantageous. In this case, the device has an interface for connecting the communication device to the local terminal, so that it can be functionally coupled to the communication device. The device can then be connected to any terminal,
For example, a telephone or a call answering device is connected to a local terminal of the communication device. Signal transmission or powering also takes place through such interfaces in a known manner.
In applications, such devices are connected to the respective local terminals, into which incoming calls are automatically routed. In this case, the communication device must be programmed such that the call enters all other local terminals and the call is indirectly directed through the device of the present invention only by persistent relay.

It is also advantageous to integrate the switching sequence of the present invention into a telephone, wherein the connection is not made directly after a predetermined number of call codes by the user manually accepting the connection at the terminal. If so, the direct select function is only activated, as in the case of a call answering machine.
It is inventive to simulate a direct selection function by preparing a post-selection function in a communication device that cannot directly select a direct call with a unique call number to a local terminal.

[0012]

FIG. 1 is a block diagram of a communication device incorporating a device of the present invention for imitating a direct selection function. The functional connection of the individual components is indicated by arrows, the direction of the arrow indicating the direction of information flow. The communication device is
It has a telephone network connection device 1 and a relay matrix 2 according to a known method. The functions of the relay matrix 2 are controlled by a sequence control system 3, which in this embodiment controls the normal functions of the communication device and also serves a useful function for performing the method of the invention. Control signals are transmitted between the sequence control system 3 and the relay matrix 2 via the corresponding control channels 23 in both directions.

The communication device includes four local terminal connection devices 13,
14, 15, and 16, which have three premises terminals 6,
7, 8 and a call responder 9 are connected. In the case of a normal communication device, an incoming call is directed to the transit matrix 2 through the network access 1. The sequence control system 3 includes local terminal connection devices 13, 14, 15,
Determine which of the 16 calls will be relayed. In other words, it determines where in the local terminals 6, 7, 8 or the call responder 9 a control signal indicating an incoming connection is further guided. In this case, if the local terminal is a telephone, a ringing tone sounds. When the corresponding terminal is activated, for example when the handset is picked up, an external call mutual connection and a connection with the terminal are made. Thereafter, voice and other information are transmitted over the connection between the external caller and the terminal.

The simulation of the direct selection function or the preparation of the post-selection function when implementing the switching sequence of the present invention is performed as follows. The communication device is connected to the telephone test network via the telephone connection device 1 in a known manner. First, an incoming call is accepted by the internal transit matrix 2 activated by the sequence control system 3.
The sequence control system 3 then receives the signal from the relay matrix 2, which indicates an incoming connection and sends a control signal via the data line 23, which acts on the relay matrix 2 to accept the connection.

The sequence control system 3 further outputs a notification sentence from the voice component memory 5 by a control signal transmitted via the data line 24. As a result, a connection is first made between the voice component 5 and the relay matrix 2 and to an external caller, so that voice information can be transmitted. The notification text is primarily user defined and stored in digital form in the audio component memory. Such voice information is sent directly to the relay matrix via the data line 27 so that a remote caller can receive it as an acoustic signal. In the meantime, the sequence control system 3 adjusts the relay matrix 2 so that the welcome text is transmitted to the remote subscriber. An operation guide for post-selection is transmitted to the distant subscriber in a welcome text. The caller is required to enter certain post-selection instructions that include the identification of the local terminal to be selected. The caller is informed which subscriber can be obtained with which code or which key command.

After the welcome greeting and the guidance for use, the connection between the audio component memory 5 and the relay matrix 2 is disconnected and the connection of the relay matrix 2 for the identification unit 4 is made. The connection between the audio component memory 5 or the identification unit 4 and the relay matrix 2 can also be parallel. This has the advantage that the experienced user can enter the post-selection command without waiting for the complete welcome text.

Information entering the communication device via data line 28 is transmitted to identification unit 4 via data line 26. After the caller enters, the selection command is transmitted to the identification unit 4, which can identify the information. The identification unit 4 includes a multi-frequency receiver or a voice identifier, or FIG.
Are included. In this case, a signal that can be identified and processed by the identification unit as the post-selection command becomes a problem. The multi-frequency code signal, for example a DTMF signal, is converted into a digital electronic control signal in a known manner and transmitted to the sequence control system 3. In the case of a speech identifier, the speech signal is compared to a speech signal pattern taught during a predetermined training phase. The speech identifiers in this case are mainly phoneme-based, speaker-independent speech identifiers, for example HMM speech identifiers. The characteristics of a specific local terminal are assigned to the predetermined voice pattern. The features of the identified voice pattern are transmitted to the sequence control system 3 by the identification unit 4 as digital electronic control signals. Thereby 2
In one case, the sequence control system is informed via a local terminal to choose. The electronic control signal generated by the identification unit 4 corresponds directly to the number of the local terminal to be selected or is explicitly assigned to the station.

The sequence control system further generates a relay signal by taking in the number of the local terminal to be selected, which is transmitted to the relay matrix 2 via the data line 23. These signals are the same as those additionally generated by the same communication device during manual relaying by a terminal connected to the local terminal. By means of the relay matrix, these relay signals act to establish a connection to the local terminal to be selected and to a previously created first connection to the remote subscriber. While the connection to the local terminal to be selected by the communication device is being established, the external connection is basically grounded, with the caller sometimes playing pause music or the like. This provides a direct select function for remote subscribers.

If the connection to the selected local terminal is not accepted within a predetermined time or after a predetermined number of bell codes, the connection is disconnected again by the relay matrix 2 to the selected local terminal. Is done. The caller is guided from the relay matrix 2 to the call responder 9 by a control signal generated by the sequence control system 3. The post-selection function may be made available again. That is,
Controlled by the sequence control system 3, a new post-selection is requested by the remote caller via the voice component, the incoming post-selection command being processed in the manner already described, and a relay signal being generated. Will be done. By post-selection, the caller, if such a connection, has a call answerer 9
Can be connected directly to

FIG. 2 shows the structure of the device 17 of the present invention as an adaptive example, which is the local terminal connection 16 'of the communication device.
Can be connected to In that case, the communication device is not structurally changed, so that a known device already in operation can be provided with a post-selection function using such an adapter 17 of the invention. The components of the communication device are shown schematically in the upper part of FIG. 2, and the components of the adapter 17 are shown in the lower part of FIG. 2, the connection of the individual components being indicated by arrows. . The function of the individual components essentially corresponds to that of the device of FIG. 1, the function of the sequence control of FIG. 1 being carried out by the sequence control system 3 'of the adapter in the device shown in FIG. Undertaken by The controller 12 controls functions such as call acceptance of communication devices, bridging between local terminals, and disconnection in a known manner. The sequence control system 3 'controls the function of the adapter 17 of the present invention. The adapter is constituted by the sequence control system 3 ', the identification unit 4', the voice component memory 5 ', the call answering component 10, the interface 11 and the data lines (23' to 27 ') between the individual components.

The communication device shown in FIG. 2 has four local terminal connection sections 13 ', 14', 15 'and 16', three of which are connected to conventional local terminals 6, 7, and 8. The device 17 of the present invention is a local terminal connection unit 1 of a communication device as an external device.
6 '. Data transmission between the communication device and the adapter 17 takes place via a conventional data line 29, which is laid for the transmission of voice signals and control signals. Signal transmission can be performed on separate voice and control channels, but also on a common channel, in which case control and usage information are distinguished by signal type. In the latter case, the control signal is, for example, a multi-frequency code signal, which is transmitted like speech.

In order to be able to simulate the direct selection function, all external calls must first be relayed by the communication device to the local terminal connection 16 'and then to the adapter 17. The controller 12 includes the relay matrix 2
Is programmed to first relay all incoming connections in this manner. The incoming connection is sent to the adapter 17 via the interface 11. Data line 29
Transmitted via the interface 11 to the sequence control system 3 'and the identification unit 4' via the data line 23 'or 26'. The sequence control system 3 'processes control information included in the transmission signal, and the identification unit 4' processes audio information included in the transmission signal.

The sequence control system 3 'sends a control signal to the communication device via the interface 11, and the signal notifies that a connection has been made. At the same time, the sequence control system 3 ′ causes the notification message to be output from the voice component memory 5 ′,
It is led via 7 'to the interface 11, where it is coupled to the data line 29 as an audio signal in electronic form. The connection between the voice component memory 5 'and the relay matrix is connected to an external connection, so that the caller can receive the notification message as an acoustic signal.

After the caller enters the selection command, it is linked to the connection between the relay matrix 2 'and the adapter 17 via the incoming connection, as described above. Interface 11
Then, the incoming audio signal enters the input unit of the identification unit 4 '. The identification unit 4 'provides an identification result in the manner described above, which is transmitted via the data line 25'. This creates a relay signal, which is transmitted via the interface 11 to the communication device. When receiving such a relay signal, the controller 12 causes the relay matrix 2 'to establish a connection with the selected local terminal. Once such a connection has been established, the connection via the telephone network connection 1 'is linked to the connection of the connection matrix 2' to the selected local terminal. At that time, the connection of the relay matrix 2 ′ to the adapter 17 is disconnected. The external caller is thereby automatically connected to an available local terminal with the help of the adapter 17.

If the selected local terminal does not respond, that is, if the connection of the relay matrix 2 'to the local terminal is not successful, the corresponding notification message from the voice component memory 5' is discarded and the sequence is terminated. The control system 3 'requests the user to input the post-selection command again. The external connection that is expected to be relayed is taken from ground by the corresponding control signal by the sequence control system 3 'and reconnected with the adapter. Such a post-selection instruction may result in the selection of a paging transponder connected to other local terminals or the paging transponder component 10 integrated with the adapter. A call to a distant caller without new notification may be directed directly to the call answering component 10. In addition, the adapter connects from the interface 11 to the call answering component 1
It has a data line 26 "to 0, through which the call answering component is placed in parallel with the identification unit 4 '.
This data line 26 "is available in both directions for conversation and listening of the call answering machine.

The call answering machine memory is mainly divided by a storage area, in which information is stored according to the specifications of the local terminal.
FIG. 3 schematically shows the structure of the identification unit 3 '. This identification unit has a multi-frequency receiver 21 and a voice identifier 22,
They are connected in parallel. Two components 21,
The entrance side of 22 is connected to the voice channel of the communication device. The caller thereby inputs the post-selection command as a multi-frequency code signal and a voice signal. After being entered, the selection command is sent to a multi-frequency receiver 21 and a speech identifier 22, where those components send out the identification results as electronic control signals that match the input signal. Other components do not send out output signals.

Further, the sequence control system requests the user to input the post-selection command again when the identification unit cannot identify the post-selection command.
